  3. 3. Today A note on coding standards Defining “Post Types” or “Content Types” Give an example of Custom Post Types Open up to questions about Custom Post Types
  4. 4. Coding Standards Coding standards are very very important If you’re releasing a public plugin, things can go wrong if you don’t use namespaces The biggest problem with the plugin repository is a lack of following coding standards Version control. Version control is important (<3 git)
  5. 5. Namespacing Prepend function names with something - anything! For example, an events plugin - could use evnt_show_events instead of just show_events This is good - you avoid conflicts! show_events is bad
